Vanyuwa [196]

Answer: A.Santa Ana

Explanation:

This description perfectly agrees with the Santa Ana Winds (also called Santana Winds), which are due to a meteorological phenomenon that occurs between southern California and northern Baja California during autum and early winter (although they can also occur in the other seasons of the year). In this sense, strong winds are caused by high air pressure circulating clockwise at high altitudes in the Great Basin between Sierra Nevada and the Rocky Mountains (and the Mojave Desert).

It should be noted that these winds are characteristic of the region, which dry the vegetation, knock down electric utility poles and trees, and sometimes transport hot embers, being the main cause of fire spread.
